Stereoscopic image display

A method, comprising:

• determining a location of eye pupils of a viewer;
• displaying an image within a first focus for viewing with a left eye of a viewer;
• displaying the image within a second focus for viewing with a right eye of the viewer;
• tracking a positional change of the eye pupils of the viewer;
• and
• generating a sequential image corresponding to the positional change of the eye pupils, the sequential image including a motion parallax depiction of the image for stereoscopic viewing.

An eye pupil tracking system, comprising:

• a first illumination source configured to illuminate eyes such that eye pupils retroreflect infra-red light from the first illumination source;
• a first camera configured to image retroreflected infra-red light which corresponds to a location of the eye pupils;
• a second illumination source configured to illuminate the eyes such that the eye pupils retroreflect infra-red light from the second illumination source, the second illumination source further configured to alternate illumination of the eyes with the first illumination source;
• a second camera configured to image retroreflected infra-red light which corresponds to the location of the eye pupils;
• and
• viewer position logic configured to compare a first camera image and a second camera image to determine the location of the eye pupils.

A method, comprising:

• illuminating eyes with a left on-axis illumination source such that eye pupils retroreflect infra-red light from the left on-axis illumination source;
• illuminating the eyes with a right off-axis illumination source such that the eye pupils do not retroreflect infra-red light from the right off-axis illumination source;
• capturing a first image set with a left camera and a right camera, a left camera image including retroreflected infra-red light which corresponds to a location of the eye pupils;
• illuminating the eyes with a left off-axis illumination source such that the eye pupils do not retroreflect infra-red light from the left off-axis illumination source;
• illuminating the eyes with a right on-axis illumination source such that the eye pupils retroreflect infra-red light from the right on-axis illumination source;
• capturing a second image set with the left camera and the right camera, a right camera image including retroreflected infra-red light which corresponds to the location of the eye pupils;
• and
• comparing the left camera image and the right camera image to determine the location of the eye pupils.

A method, comprising:

• illuminating eyes with a first illumination source such that eye pupils retroreflect infra-red light from the first illumination source;
• capturing a first image set with a first camera and a second camera, a first camera image including retroreflected infra-red light which corresponds to a location of the eye pupils;
• illuminating the eyes with a second illumination source such that the eye pupils retroreflect infra-red light from the second illumination source;
• capturing a second image set with the first camera and the second camera, a second camera image including retroreflected infra-red light which corresponds to the location of the eye pupils;
• and
• comparing the first camera image and the second camera image to determine the location of the eye pupils.

One or more computer readable media comprising computer executable instructions that, when executed, direct a stereoscopic image display device to:

• determine a location of eye pupils of a viewer;
• display an image within a first focus for viewing with a left eye of a viewer;
• display the image within a second focus for viewing with a right eye of the viewer;
• track a positional change of the eye pupils of the viewer;
• and
• generate a sequential image corresponding to the positional change of the eye pupils, the sequential image including a motion parallax depiction of the image for stereoscopic viewing.

A stereoscopic image display system, comprising:

• means for determining a location of eye pupils of a viewer and for tracking a positional change of the eye pupils of the viewer;
• means for displaying an image within a first focus for viewing with a left eye of a viewer;
• means for displaying the image within a second focus for viewing with a right eye of the viewer;
• and
• means for generating a sequential image corresponding to the positional change of the eye pupils, the sequential image including a motion parallax depiction of the image for stereoscopic viewing.
